同时，熔体流动速率控制偏高也是一个原因。
任何两点间的热流动速率则随温差的加大而增加。
The rate of heat flow between any two points increases with difference of temperature.
首先是冷却剂的温度升高，然后温度随冷却剂流动速率变化。
The temperature rise in the coolant then becomes a function of coolant flow rate.
该材料在不需要衬底加热的情况下于室温即具有快的流动速率。
It has fast flow at room temperature without pre-heating the substrates.
该材料在不需要衬底加热的情况下于室温即具有快的流动速率。
